COBB Tuning Fuel Rails

Not Yet Reviewed

Upgrading your fuel system is required in order to take advantage of airflow modifications such as intakes, exhausts, or turbochargers. The COBB fuel rails allow for increased fuel capacity and consistent performance at each injector. They are constructed of 6061 billet aluminum and feature a black anodized finish with a laser-etched COBB logo. Each rail comes with adapters pre-installed to allow for plug-and-play installation with the COBB fuel line kit. Phenolic thermal spacers and stand-offs provide a heat barrier between the cylinder head and fuel system and are included with each kit.
